The charm of the oleander
The oleander , known in Italy as oleandro, is a beloved shrub for its colorful flowers that adorn gardens and terraces. This decorative element finds its ideal habitat in regions with mild and sunny climates, where it can best express its beauty and vigor. Its ability to adapt to different climatic conditions makes it a popular choice for gardeners and botany enthusiasts.
The importance of pruning
Regular pruning of the oleander is crucial for keeping the shrub healthy and lush. This practice helps stimulate the growth of new shoots and improve blooming. Pruning, when done correctly, allows the shrub to maintain a harmonious shape and prevents issues related to air circulation and disease spread.
When to prune
The timing of pruning is a determining factor for the success of oleander care. In general, pruning should be done at the end of winter or the beginning of spring. In the southern regions of France, the ideal period is between the end of February and March, while in the central and northern parts of the country, it is recommended to wait until March or April. In gardens located at higher altitudes, pruning can be postponed until April. It is important to avoid pruning during autumn and winter to not compromise the health of the shrub.
Pruning techniques
Pruning the oleander should be annual if the shrub is planted in the ground and biennial if grown in a pot. During pruning, it is essential to remove dead and damaged branches and thin out the center of the shrub to improve air circulation. It is recommended to reduce the branches by about one-third to encourage branching and achieve denser and more uniform growth. Cuts should be made above an outward-growing bud, at a 5 mm diagonal angle, to prevent water accumulation and rot. It is crucial not to remove more than one-third of the foliage during a single pruning session.
